5. Find the equation for each graph. a) b) 2 42 0.5

Solution

it is a sine wave with a period 6pi so value od B=2pi/6pi

hence B=1/3 and here amplitude is 2

so, f(x)=2sin (x/3) is our required function

b) in this our period is 2 so B=2pi/2=pi

and amplitude is 0.5

so function is given by f(x)=.5cos(pi* x)
